The Sony HVL-20DW2 20W Video Light is switchable between 10W and 20W. Designed to mount onto the camcorder's accessory shoe, the HVL-20DW2 provides 10W operation when used with an NPF-550 InfoLithium battery, and 20W operation when used with NP-F750 or NP-F960 InfoLithium batteries (batteries must be purchased separately).
Note! Camcorders without an accessory shoe require the optional VCT-S30L shoe bracket.
Sony NPF-730, NPF-750, and NPF-950 batteries are the only ones that will work in the 20W mode.
10 Watts or 20 Watts can be selected by the user.
